AC Nexus Advanced Power Distribution & Ground Enhancement System: $20,000 ★
Steve McCormack, once the proprietor of The Mod Squad, is the man who introduced the concept of accessory isolation feet—his Tiptoes were aluminum cones with flat tops and sharply pointed feet. Now he's brought to market this passive AC-power filter, whose Panzerholz enclosure contains two fist-sized silver-conductor capacitors from Duelund. The IEC AC inlet is a Bocchino Audio Marriner10 and the AC outlets are four Furutech Nano Crystal Formula duplexes. Four Cardas ground posts…

DaySequerra FM Reference Signature Modification: $3800 (+ cost of tuner) ★
David Day's Signature Mod effectively addresses this ultimate FM tuner's cathode-ray tube's tendency to burn out. Switching circuitry has been added to allow the CRT to turn off when not needed. The Signature Mod also replaces the tuner's incandescent bulb with longer-lasting LEDs, and uses hand-matched, low-group-delay filters for lower distortion and better channel separation. LG noted punchy, quick bass response, a deeper soundstage, and a more transparent midrange. "The new CRT'…

Chord Hugo M Scaler: $5650
The Chord Hugo M Scaler is a digital processor but not a digital-to-analog processor, its purpose being the upsampling—referred to in the UK as upscaling—of incoming data. When connected to a Chord DAC via BNC connectors, the M Scaler can upsample up to 705.6kHz or 768kHz, but with non-Chord DACs the upper limits become 176.4kHz and 192kHz. (In all cases, incoming DSD data is converted to PCM, with a 6dB reduction in level.) JA used the M Scaler with Chord's DAVE D/A processor, and with his own PS Audio and Mark Levinson DACs.…

Audio Research Tube Damping Rings: $5 each
Damping rings for all AR products are now available to the public at large. They're made of a proprietary polymer material that converts kinetic energy to heat, and their improvements are not subtle, exclaims BJR: tighter, cleaner, deeper, more dynamic bass; more coherent transient attacks; crisper, more extended highs; plus "improvements in the reproduction of subtle gradations of low-level dynamics." Give 'em a whirl—the cost is minimal. (Vol.23 No.2, Vol.26 No.8)

Channel D Pure Music software: $129 ★
Pure Music (Mac only) can play sampling rates of up to twice the 192kHz limit of Amarra and Decibel. Like those programs, Pure Music (Mac only) offers memory play, automatic sampling-rate changes, and full compatibility with native FLAC files and in its latest version, DSD files. Going from iTunes to Pure Music, the sonic improvement was modest but worthwhile, with cleaner trebles and improved pitch certainty. Compared with the less expensive Decibel, however, Pure Music lacked some openness and clarity, decided AD. Using Pure…
Audioquest Dragon, XLR: $11,900/1m pair
RCA: $9500/1m pair
Uses "Solid Perfect-Surface Silver (PSS)" conductors with a dielectric comprising fluoropolymer air tubes. MF compared the balanced Dragon with his TARA Labs' "The Evolution Zero" interconnect and concluded that it was considerably more open but not brighter, faster but not leaner. (Vol.45 No.9 WWW)
AudioQuest ThunderBird XLR: $3900/1m pair
RCA: $2900/1m pair
When he substituted the balanced Thunderbird for his previous interconnect, HR wrote that his system's sound changed so dramatically…
Audioquest Dragon Zero: $27,500/8' pair
"Notably transparent, able to deliver dynamic slam and detail," wrote MF. (Vol.45 No.9 WWW)

The SC-5 has silver-coated OFC conductors (14AWG), a foam polyethylene dielectric, a PVC jacket, and an internal packet of vibration-absorbing fibers.

DH Labs Silver Sonic D-110 AES/EBU: $145/1m
(NR, but see EL's review of the Bel Canto DAC3.5VB in Vol.34 No.6 WWW)
Kimber Kable Orchid: $948/1m
Expensive, but the best AES/EBU link JA has used. J-10 loved the Orchid's midrange liquidity and detail, but preferred Illumination's S/PDIF cable overall. SD (almost) doesn't equivocate: "Probably the best out there for now. . . .A stunner!" RH and RD are also fans. New lower price usefully brings this cable in reach of more music lovers. (Vol.19 No.5)
